Abstract: One of priority problems of modern agricultural production is preservation of soil resources in this connection search of effective ways of return of the thrown sites to structure of an arable land is necessary. This process is expensive, but invested funds will be paid with a harvest of grain crops which usually cultivate in the first year after development of laylands. A condition of a deposit on structure of a biocenosis variously depending on age of a deposit and genesis of soils. Violation of the natural balance in the soil deposits in the reduction of arable land is accompanied by changes in organic matter content, the total number of microorganisms and other properties. The article presents the results of field experience for plowing grass deposits at different depths and calculations of economic efficiency of production of cereals during the development of deposits of sites of varying degrees of overgrowth. It was found that over the 25-year period the lack of agronomic treatments on deposits of gray forest soil humus carbon content increased more than 1.7 times. The best reception, minimally reducing the intensity of mineralization of organic matter and do not affect the soil micro flora is Reversible shelling by 10-12 cm as the main reception plowing deposits. The highest profitability of grain production after the development of the overgrown areas obtained on the gray and dark gray forest soils (36-48‰) at the initial stage of overgrowing their grassy vegetation.
